A couple of years ago I was running the XX4 full time and on astro I got the TLR modern big bores. I worked with them for ages trying to get them right then one day I just stuck the WE original shocks on and went a second a lap faster. I didn't look back and went onto finish 5th at a regional, my best ever result to that date and the car was just awesome! I would also suggest the tough racing belts along with a full fresh set of pulleys including the clicker pulley and you'll be away. It can still compete with the top cars, cos its the BEST!
